Pelco Manual C1927M (5/99) 7Figure 2. Multiplexers with KBD4000 Keyboard
By adding a KBD4000 keyboard to the multiplexer (refer to Figure 2), you can control 1-16
multiplexers from up to 25 feet (7.6 m) away with the cable supplied with the keyboard.
Greater distances between the multiplexer and keyboard can be obtained if you provide a
Pelco KBDKIT(-X) and your own cable.
A keyboard also gives you the added capability of controlling moveable cameras. Control
systems for moveable cameras must be Coaxitron® compatible. In Figure 1 cameras are
fixed.
The systems shown in Figures 1 and 2 are for a single operator only. To permit up to four
operators to use the system, an MX4000SVR multiplexer server can be added, as shown in
Figure 3.
The main and spot monitor outputs from each multiplexer are connected to the server,
providing two video channels. The design is not a true matrix, however, because only two
operators (instead of all operators in a true matrix ) can select cameras from the same
multiplexer at the same time, one operator using the main monitor and the other operator
using the spot monitor.

NOTE:
The KBD4000 key-
board in combination with a
multiplexer provides
Coaxitron
®
control of pan,
tilt, and lens functions.
When used with 15-bit stan-
dard Coaxitron
®
receivers,
such as the CX9000 Series,
the PT7700, and the ED25/
27/28/29, the KBD4000 key-
board in conjunction with a
multiplexer supports all pan,
tilt, and lens functions, and
AUX on/off. The keyboard
will not set or call presets or
support preset scanning.
When used with 32-bit ex-
tended Coaxitron
®
receivers,
such as Intercept
®
, Spec-
tra
®
, and LRD41C21/
LRD41C22 Series, the
KBD4000 keyboard in con-
junction with a multiplexer
will support all the functions
of a 15-bit receiver, includ-
ing the setting and calling of
presets and patterns. It will
not support programming of
labels for presets or pat-
terns. If labels for presets or
patterns are required, they
would need to be pro-
grammed with a different
control, such as the
MPT9500.
